We have a bobcat 743b. The bucket will tilt down but not up. We already replaced the o-rings in the valve body but it didnt solve the issue. Suggestions.
Did this just start happening all of the sudden or is it something that was intermittent? if it just happened one day check and make sure your AUX hydraulics isn't on(right stick pushed right).
Also check the piston didnt come off in one of the cylinders
That was one of my first thoughts also but wasn't sure how specific the OP was about function and terminology of the machine parts.
743 uses 1 cylinder for the bucket. Would wager the seals are totally blown. Ed
